Key Points

This study aims to evaluate the effectiveness of ASL MRI in detecting residual brain AVM perfusion and its prognostic value following gamma knife radiosurgery.
Conducted a retrospective multicenter study of adult patients with brain AVMs treated with gamma knife radiosurgery from 2015 to 2024.
Analyzed follow-up MRIs including ASL perfusion sequences compared to conventional MRI and digital subtraction angiography (DSA).
Calculated diagnostic accuracy metrics and assessed prognostic value of ASL ratios for nidus obliteration over time.
ASL exhibited higher sensitivity (88.9%) and specificity (88.6%) compared to conventional MRI sequences.
Quantitative ASL ratios effectively distinguished residual shunting and predicted time to obliteration.
Serial reductions in ASL ratios were significantly associated with progressive bAVM involution (p < 0.01).
